Redirected from Computer algebra A computer algebra system (CAS) is a software package which facilitates symbolic mathematics . Typically, these systems include

arbitrary precision ( bignum ) arithmetic, allowing for instance to evaluate pi to 10,000 digits. symbolic manipulation engine, to simplify algebraic expressions, differentiate and integratefunctions and solve equations graphing facility, to produce graphs of functions, typically in two and three dimensions linear algebra subsystem, to allow matrix computations and solving of systems of linear equations high level programming language , allowing the user to implement their own algorithms

The study of algorithms useful for computer algebra systems is known as computer algebra The run-time of numerical programs implemented in computer algebra systems is normally longer than that of equivalent programs implemented in systems such as MATLABGNU octave[?] or directly in C , because the computer algebra languages are interpreted and the bignum system may cause overhead.

8. GAP In Emacs And Xemacs PATH1 is the path to the GAP script which you use to start GAP (for example, PATH1=/home/wdj/computer_algebra/gap4r4/bin)http://cadigweb.ew.usna.edu/~wdj/gap/gap_emacs.html

GAP in emacs and xemacs

This html describes how to run GAP in emacs or xemacs. It first assumes that the user is running GAP on a linux/unix machine. The second part considers the windows case. The gap mode file was written by Goetz Pfeiffer and Michael Smith. This webpage was written with help from Gary Zablackis, Nikos Apostolakis, Ric Crabbe, and Steve Linton. Note that under emacs/xemacs you may lose the tab-completion (but see below for Nikos' fix for this) and the nice history features of GAP's built-in shell. However, as a small consolation, you can edit out any syntax mistakes in your session as you go and emacs has it's own search function, which serves as a replacement for GAP's history feature. Gary Zablackis points out that the gap-help-filter code, given in the windows part below, is probably relevant to all users of Emacs with GAP 4.4.x (and possibly earlier), as the GAP output changed from "[space] more" to "[space] page, ..." at some point, and the *Help* buffer seems to be read-only without the addition I made.

BibSonomy Blog

Feature of the week: interactive tutorials and new help structure On 12th April 2007 it is BibSonomy's birthday :-) Two years of design, development and the contribution of its users have enhanced the system constantly. In order to show BibSonomy's features and support users starting to work with the system, we have changed our help-websites. * A general overview of all help functionality we offer can be found at: http://www.bibsonomy.org/help/ * A special highlight are the interactive tutorials making basic and complex actions in BibSonomy easy to understand (thank you Christian!): http://www.bibsonomy.org/help/tutorials * Users who want to get the most of BibSonomy can find tips, tricks and useful tools at: http://www.bibsonomy.org/help/addons * Finally, we want to give more background information on what is going on behind and around BibSonomy: http://www.bibsonomy.org/help/about
